0x815Kyiv says Ukrainian forces liberated Robotyne in Zaporizhzhia region, Robotyne was one of three Russian lines of defence in this area
raikThe russian lines of defence have dragon teeth and anti-tank ditches i have heard. So, they are about 5 kilometres away from the first line. They are getting close.
Limes of defenses generally come in layers, with the more strongly prepared ones being further back. So it sounds like the ultrasound have broken through the first line of defense.
Lines of defences have a security zone. That is where ukranians are. Close to the first line.
with the more strongly prepared ones being further back
Reportedly the reverse is true for the Russian defences, hence also why Russians didn’t readily retreat from the first one but tried to exert influence over the grey zone instead.
